Max/Min Input Limits CRIO

[MattViewX.007]

Hey Guys,

I have a question about adjusting the Max/Min Input Limits on an analop input card for a CRIO to improve measurement precision.  I know this feature is available through the DAQmx drivers but I haven't found a way to do it with it plugged into my CRIO....

Thanks

Matt

Hi Guy,

you may try to find those settings in the module properties by right-clicking the module in the project tree.

Or you use property nodes, atleast in the FPGA they are available.

Can't check this as I don't have access to a cRIO project right now…

Nope.... I have tried that and nothing in those options that I see.  Or any of the FPGA config nodes....

Hi MattViewX.007,

On the RT side, you could select AI Channel Settings in the Read/Write Control. On the FPGA side, there is the Set Voltage Range method with the FPGA I/O Method Node. For examples of their implementation, I would recommend one of the module specific examples in the Example Finder by going to Help>>Find Examples and then Hardware Input and Output>>Compact RIO>>Module Specific IO>>Analog Input.
